Abstract
Description
Technical Field
[0001] This utility model particularly relates to a shrimp larvae cultivation system. Background Technology
[0002] In traditional shrimp larvae rearing, polyculture of mother shrimp and shrimp larvae in ponds has been a long-standing practice. This method faces the following technical bottlenecks:
[0003] (1) Severe biological loss: When starving, female shrimp will actively prey on shrimp larvae with weak swimming ability. Studies have shown that in unsorted mixed culture ponds, the mortality rate of shrimp larvae due to predation by female shrimp can reach 30%-45%.
[0004] (2) Risk of physical damage: The violent water flow and limb collisions generated by the activity of adult female shrimp can easily cause shell damage or internal organ compression to the shrimp larvae, leading to death.
[0005] (3) Competition for growth space: Female shrimp preferentially occupy oxygen-rich areas and food resources, resulting in slow development of shrimp larvae and a decrease in the uniformity of the group.
[0006] Existing solutions mainly rely on manual sorting at the later stage, but this has significant drawbacks:
[0007] (1) Operational damage: During the sorting process, the scraping of nets and stress from being out of water can cause mechanical damage and mortality of 5%-8% in shrimp larvae;
[0008] (2) Time lag: The optimal sorting window period conflicts with the molting cycle of shrimp larvae, making it difficult for manual sorting to accurately grasp the timing.
[0009] (3) Cost pressure: Each mu of aquaculture pond requires 3-5 laborers to carry out continuous operations, resulting in high sorting costs. Utility Model Content

[0032] A shrimp larvae cultivation system, referring to Figures 1-4 The system includes a rearing pond 1, which is equipped with a screen assembly for dividing the rearing pond 1 into a female shrimp mixing area 11 and a shrimp larvae rearing area 12. The screen assembly is equipped with filter mesh holes that allow only shrimp larvae 1-1 to enter the shrimp larvae rearing area 12 from the female shrimp mixing area 11. The screen assembly is equipped with a fixed frame 3 on both sides, which is fixedly connected to the rearing pond 1. The screen assembly is equipped with a horizontal connecting member 4, and the fixed frame 3 is equipped with a vertical connecting member 5. After one end of the horizontal connecting member 4 is inserted into the fixed frame 3 in a horizontal direction, the lower end of the vertical connecting member 5 extends into the fixed frame 3 to form a cross-shaped interlocking structure with the horizontal connecting member 4. The fixed frame 3 is equipped with an anti-detachment component to limit the rotational displacement of the vertical connecting member 5.
[0033] Furthermore, the interlocking structure of the transverse connecting member 4 and the vertical connecting member 5 includes: a slot 41 provided on the transverse connecting member 4; after the transverse connecting member 4 passes through the fixing frame 3, the lower end of the vertical connecting member 5 is inserted into the slot 41 to form an interference fit; a locking nut 51 is threadedly connected to the end of the transverse connecting member 4 extending out of the fixing frame 3; and the inner end face of the locking nut 51 is press-fitted with the outer wall of the fixing frame 3.
[0034] Furthermore, the anti-detachment component includes a rotating platform 61 rotatably mounted on the top of the fixed frame 3. The vertical connecting member 5 is connected to the rotating platform 61. The rotating platform 61 is symmetrically provided with radial abutment grooves 62. The fixed frame 3 is provided with locking members 63 corresponding to the radial abutment grooves 62. The rotating platform 61 drives the vertical connecting member 5 to rotate synchronously. When the locking member 63 abuts into the radial abutment grooves 62, it restricts the rotational freedom of the rotating platform 61.
[0035] Furthermore, the rotating platform 61 is provided with a mounting slot 7 for mounting the rotating platform 61.
[0036] Furthermore, the locking element 63 is a screw.
[0037] Furthermore, the screen assembly includes a screen 81, rigid fixing plates 82 symmetrically arranged on both sides of the screen 81, the transverse connecting member 4 connected to the rigid fixing plate 82, and the screen 81 having its two sides covered and fixed within the rigid fixing plate 82.
[0038] Furthermore, the screen assembly also includes multiple uprights 9, which are spaced apart along the length of the screen 81; the uprights 9 are fixedly connected to the screen 81 by detachable straps to prevent the screen 81 from sagging.
[0039] The working principle of this utility model is as follows:
[0040] like Figure 1 As shown, this shrimp larvae 1-1 rearing system includes a rearing pond 1 (the rearing pond contains water; in practical applications, a pond can be selected as the rearing pond). A screen assembly is installed in the rearing pond 1, which divides the rearing pond 1 into a female shrimp mixing area 11 and a shrimp larvae rearing area 12. The filter mesh on the screen assembly only allows shrimp larvae 1-1 to enter the shrimp larvae rearing area 12 from the female shrimp mixing area 11, thereby achieving effective separation of female shrimp 1-2 and shrimp larvae 1-1. This facilitates the growth of shrimp larvae 1-1 in a relatively independent environment and improves the survival rate. (It should be noted that some shrimp larvae will swim back to the female shrimp mixing area 11, but most shrimp larvae will swim through the filter mesh to the shrimp larvae rearing area 12 and will not swim back to the female shrimp mixing area 11. The main purpose of this application is to separate most of the shrimp larvae from the female shrimp mixing area 11, providing more space for the growth of the shrimp larvae, while reducing the amount of shrimp larvae 1-1 preyed upon by female shrimp 1-2.) The shrimp larvae rearing system of this application divides the rearing pond 1 into a female shrimp mixing zone 11 and a shrimp larvae rearing zone 12 through a screen assembly. Only shrimp larvae 1-1 are allowed to enter the shrimp larvae rearing zone 12 from the female shrimp mixing zone 11, effectively preventing female shrimp 1-2 from preying on shrimp larvae 1-1 when they are hungry, and reducing the mortality rate of shrimp larvae 1-1 caused by predation by female shrimp 1-2. The screen assembly separates female shrimp 1-2 from shrimp larvae 1-1. The violent water flow impact and limb collisions caused by the activities of adult female shrimp 1-2 are mainly confined to the female shrimp mixing zone 11. In the relatively independent rearing zone, the risk of shrimp larvae 1-1 dying from shell damage or internal organ compression is greatly reduced. This provides shrimp larvae 1-1 with a relatively independent and resource-concentrated rearing space. Female shrimp 1-2 no longer preferentially occupy oxygen-rich areas and food resources, and shrimp larvae 1-1 can fully obtain the oxygen and nutrients required for growth. In addition, the system eliminates the need for manual sorting in the later stages, saving the sorting costs that require 3-5 workers per acre of aquaculture pond for continuous operation. At the same time, it increases the survival rate of shrimp larvae by 1-1, thereby reducing the overall aquaculture cost, improving aquaculture efficiency, and providing strong support for large-scale aquaculture.
[0041] The screen assembly has fixed frames 3 on both sides, which are fixedly connected to the breeding pond 1 to provide stable support for the screen assembly. The screen assembly has a horizontal connecting member 4, and the fixed frame 3 has a vertical connecting member 5. One end of the horizontal connecting member 4 is inserted into the fixed frame 3 in the horizontal direction, and the lower end of the vertical connecting member 5 extends into the fixed frame 3 to form a cross-shaped interlocking structure with the horizontal connecting member 4. This structural design enhances the connection stability between the screen assembly and the fixed frame 3, prevents the screen assembly from shaking or shifting during use, and ensures the smooth progress of the shrimp larvae 1-1 breeding process.
[0042] To prevent the vertical connecting component 5 from rotating, the fixing frame 3 is equipped with an anti-detachment component. For example... Figure 3 and Figure 4 As shown, the anti-detachment component includes a rotating platform 61 rotatably mounted on the top of the fixed frame 3, and a vertical connecting member 5 connected to the lower end of the rotating platform 61. Radial abutment grooves 62 are symmetrically arranged on the rotating platform 61, and a locking member 63 corresponding to the radial abutment grooves 62 is provided on the fixed frame 3. The shape and size of the radial abutment grooves 62 should match the locking member 63 to ensure a locking effect. The locking member 63, such as a screw, is installed on the fixed frame 3, and its position corresponds to the radial abutment grooves 62 on the rotating platform 61. The rotating platform 61 drives the vertical connecting member 5 to rotate synchronously. When the locking member 63 abuts into the radial abutment groove 62, it restricts the rotational freedom of the rotating platform 61, thereby effectively restricting the rotational displacement of the vertical connecting member 5 and further improving the stability of the structure. An installation groove 7 is provided at the bottom of the rotating platform 61 to facilitate the installation of the rotating platform 61.
[0043] Furthermore, the interlocking structure between the transverse connecting member 4 and the vertical connecting member 5 includes a slot 41 provided on the transverse connecting member 4. After the transverse connecting member 4 passes through the fixing frame 3, the lower end of the vertical connecting member 5 is inserted into the slot 41 to form an interference fit. The end of the transverse connecting member 4 extending out of the fixing frame 3 is threadedly connected to a locking nut 51. The inner end face of the locking nut 51 is pressed against the outer wall of the fixing frame 3. This fit not only enhances the tightness of the connection, but also facilitates installation and disassembly.
[0044] Regarding the structure of the screen assembly, such as Figure 3 As shown, the screen assembly includes a screen 81, rigid fixing plates 82 symmetrically arranged on both sides of the screen 81, and transverse connecting members 4 connected to the rigid fixing plates 82. The two sides of the screen 81 are covered and fixed within the rigid fixing plates 82. This design gives the screen assembly high structural strength and stability. In addition, the screen assembly also includes multiple uprights 9, which are spaced apart along the length of the screen 81. The uprights 9 are fixedly connected to the screen 81 by detachable straps to prevent the screen 81 from sagging, ensuring that the screen 81 always maintains a good working condition and extending its service life.
[0045] This shrimp larvae rearing system, through the reasonable combination and ingenious design of the above-mentioned components, achieves effective separation of the mother shrimp 1-2 and the shrimp larvae 1-1, provides a good rearing environment for the shrimp larvae 1-1, improves the survival rate of the shrimp larvae 1-1, and at the same time ensures the stability and reliability of the entire system, making it easy to promote and apply in actual aquaculture.
[0046] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
